Concrete solutions that lower both emissions and air pollution
07/04/2020 - Some common strategies to reduce the greenhouse gas emissions of concrete production could have unintended consequences for local air pollution and related health damages, according to a new study.
Electric cars better for climate in 95% of the world
07/04/2020 - Fears that electric cars could actually increase carbon emissions are unfounded in almost all parts of the world, new research shows.
Health forums: Style of language influences credibility and trust
02/04/2020 - Informations on health topics in Internet forums are often so complex that laypersons are barely able to form considered judgements on the advice. One criterion which users apply instead in...
Too much salt weakens the immune system
02/04/2020 - A high-salt diet is not only bad for one's blood pressure, but also for the immune system. Mice fed a high-salt diet were found to suffer from much more severe bacterial infections. Human...
Lower-sodium turkey breast wins sensory test over full-salt option
02/04/2020 - Food scientists produced a lower-salt processed turkey that consumers in a blind sensory test preferred to a full-salt version, according to a new study.
Researchers find way to improve cancer outcomes by examining patients' genes
02/04/2020 - Genetics researchers say a new approach could benefit all sorts of serious health conditions, and they're urging scientists to quickly pluck 'low hanging fruit' for the benefit of...
Inherited origin of prostate cancer in families
02/04/2020 - Researchers have identified haplotypes, ancestral fragments of DNA, that are associated with hereditary prostate cancer (HPC) in a first-of-its-kind genomic study made possible by the study of...
Genetic signature may identify mothers at risk for preeclampsia
02/04/2020 - Researchers have identified a genetic signature combining certain maternal and fetal gene variants that are associated with a higher risk of preeclampsia.
Artificial intelligence can help some businesses but may not work for others
02/04/2020 - The temptation for businesses to use artificial intelligence and other technology to improve performance, drive down labor costs, and better the bottom line is understandable. But before pursuing...
What are you looking at? 'Virtual' communication in the age of social distancing
02/04/2020 - When discussions occur face-to-face, people know where their conversational partner is looking and vice versa. With ''virtual'' communication due to COVID-19 and the expansive use...
The physics that drives periodic economic downturns
02/04/2020 - A professor says that the way spilled milk spreads across the floor can explain why economic downturns regularly occur. Because the economic prosperity derived from new ideas or inventions follows...
